说明：  一线通讯协议的c51例子程序源代码，很实用的好东西！(line communication protocol decoder source code examples, practical good things!)

多线程socket文件传输

分支定界算法，求解0-1整数规划，c代码，可以直接运行(c/c++ popular books forbranch and bound method to solve 0-1 linear program. algorithms)

USB communication and used to access data from mass storage devices

对于新手调试入手很快,通过32单片进行通信控制，进行图像采集(For beginners, debugging is very fast. Communication control is carried out through 32 single chip, and image acquisition is carried out.)

说明：  ROAM terrain LOD example in c++

该代码为基于STM32的平衡小车控制代码，主要作用与4个麦轮小车的电机驱动，PID控制调节使得麦轮以设定的速度转动而不产生抖动。

鸟瞰图校正，基于OPENCV的应用，可以把鸟瞰图校正为平面图。(Aerial view of the correction, based on the application of OPENCV, bird' s eye view can be corrected for the plan.)
